Service Customized Space-Air-Ground Integrated Network for Immersive Media:Architecture,Key Technologies,and Prospects
文献摘要：
The space-air-ground integrated network(SAGIN) is regarded as the key approach to realize global coverage in future network and it reaches broad access for various services.Being the new paradigm of service,immersive media (IM) has attracted users' attention for its virtualization,but it poses challenges to network performance,e.g.bandwidth,rate,la-tency.However,the SAGIN has limitations in sup-porting IM services,such as 4K/8K video,virtual re-ality,and interactive games.In this paper,a novel ser-vice customized SAGIN architecture for IM applica-tions (SAG-IM) is proposed,which achieves content interactive and real-time communication among ter-minal users.State-of-the-art research is investigated in detail to facilitate the combination of SAGIN and service customized technology,which provides end-to-end differentiated services for users.Besides,the functional components of SAG-IM contain the infras-tructure layer,perception layer,intelligence layer,and application layer,reaching the capabilities of intelli-gent management of the network.Moreover,to pro-vide IM content with ultra-high-definition and high frame rate for the optimal user experience,the promis-ing key technologies on intelligent routing and deliv-ery are discussed.The performance evaluation shows the superiority of SAG-IM in supporting IM service.Finally,the prospects in practical application are high-lighted.
